Brachymenium Regnellii and Bryum Leptotorquescens (Bryaceae) New to Suriname

Abstract

Abstract The previously Brazilian endemic species, Brachymenium regnellii Hampe, has been found in Suriname. It is a member of sect. Rostrata Ochi, distinguished from all other members of that section in Suriname by its percurrent costae. Brachymenium Schwägr. is characterized by the sporophytic features of: erect to suberect capsules; conic-apiculate to short-beaked opercula; and diplolepideous peristomes with narrow, densely papillose exostome teeth and greatly reduced endostomes. Bryum leptotorquescens Müll. Hal ex Broth., previously known from Mexico to western South America, and tropical Africa is reported from Suriname. It differs from other similar mosses in Suriname by the combination of weakly developed leaf borders; strongly decurrent leaves; and costae in cross section with well-developed stereid bands. Bryum billarderei Schwägr. is the correct spelling of that often mis-spelled name.
